If is less than the SWF file's frame rate (for example, 10 frames per second [fps] is
interval
equal to 100 millisecond intervals), the interval function is called as close in time to the value
of as possible. Executing long, memory-intensive scripts during an interval causes
interval
delays. If the function being called initiates a change to visual elements, you should use the
updateAfterEvent()
is greater than the SWF file's frame rate, the interval function is called only after
